Water cleanliness and filtration standards are rising in many parts of the world. That means municipal water treatment facilities and commercial water purification systems need to be increasingly advanced to keep up. One of the most important tools in an advanced filtration system is a microfiltration membrane.

Microfiltration membranes use physical separation processes to remove contaminant particles, reducing the need for chemical treatments. Although there are many types of filtration processes that incorporate membranes, one of the most preferred processes is pressure-driven membrane filtration, which forces liquids through a large membrane at high pressure levels.

There are four subtypes of pressure-driven membrane filtration, each of which handles particles of various sizes. These processes include:

  • Reverse osmosis
  • Nanofiltration
  • Ultrafiltration
  • Microfiltration

Microfiltration Membrane Uses

Microfiltration processes feature membranes that can block particles as small as 0.1 microns. This makes microfiltration an important first step to complex and high-purity filtration systems. By removing larger contaminants like bacteria and suspended solids, microfiltration prepares fluid streams for further treatment processes.

Microfiltration membranes are commonly used in the following applications:


  • Boiler refeeds
  • Clarifying and sterilizing water for beverage, food, and pharmaceutical industries
  • Cooling towers
  • Providing desalination pretreatments in multi-stage processes
  • Potable water treatment
  • Safer water discharge processes
  • To optimize water re-use filtration systems in industrial and municipal settings
  • Treating water at point-of-use (POU) and point-of-entry (POE) ports
  • Water reuse
  • Wastewater treatment

Microfiltration systems can be used in a diverse range of applications. Because of this, there are many membrane options to choose from to achieve the intended level of filtration. It’s important to carefully consider the level of water contamination, the housing construction and geometry of the water treatment system, the membrane material, the volume of treated water, and more when selecting the proper microfiltration membrane.

As municipalities and industrial users pursue new standards and approaches to waste water treatment, Trupor® enables new approaches to water re-use. Learn more here.
